Sufjan Stevens gives you an 'Avalanche' of Illinoise Castoffs

New Pantheon Prize winner Sufjan Stevens has taken 21 songs that didn't make it onto his prize winning album, Illinoise, and applied them towards a new album.

Due out on July 25, The Avalanche features demos, instrumentals, interludes, and unreleased songs that were recorded for Illinois but didn't make the final cut. According to Billboard, almost all of the tunes on Avalanche were originally rooted in an Illinoise track.

Illinoise is the second of Stevens' 50 'states project,' in which he plans to write an album for each of America's 50 states.
